IMPORTANT

Note on Differences between Actual MCU and Emulator:

•Operations of the emulator differs from those of mask MCUs as listed below.

(1) Initial values of internal resource data (such as a part of SFR, and RAM) at power-on

(2) Oscillator circuit

Make note of the fact that in the oscillator circuit where a resonator is connected between the

XIN and XOUT pins, oscillation does not occur because a flexible cable, buffer IC and other

devices are used between the emulator MCU and the target system.

Note on Switch Settings on the Pod Probe:

• This pod probe has three switches that need to be set according to the target system. Otherwise, the

pod probe may not operate normally or get out of order for two reasons described below. For details

on how to set these switches, refer to "3.2 Switch Settings" (page 24).

- Incorrect settings with which the pod probe operates

- Jumper switches remain removed while the pod probe operates

Note on Synchronous Designed Target Systems:

• Because this pod probe has the clock fed into the MCU via the buffer IC and flexible cable, etc.,

there is a finite delay time before the clock from the target reaches the MCU.

In target systems where the MCU and the ASIC, etc. are designed to operate synchronously, this

delay time may render the MCU and ASIC unable to operate synchronously. In such a case,

evaluate your application system using the actual MCU on the target board.
